This burner is of the .type adapted for disposal upon the fuel grate in the combustion chamherof steam boiler .furnaces, hot

water boiler furnaces, hot air furnaces; etc, etc, and it comprises the base, plate 1. that rests directly ,upon lthegfuel grateand supports the elbow-1i keair pipes2v attheir dowel ends, said plate lheing perfpratedinalign- T meat with the pipe bores to" permit the intakeof airintoi;;the said pipesthrough the grate openings and thrQllgh the plate. The said air pipes are jacketed with water and steam acket 3 which is formed with .tlie 1 integral flared orhell shaped portion 4, said jacket Ilhei11g formed also with the .rib .5

10 are tapped saidq pipe extending through the plate 8 into the dome 9 and rising almost to' lthehapex thereof and being curved or archedat its highest point and formed. with an intake opening-11 spaced away from the dome apex. Secured to thepipe 10 are the support pins 12 for the open ended cylindrical shield 13 for the float 11 disposed the'reWithi-n, said shield being formed with a plurality of, perforations -15. Depending from the float is a stem 16 that extends through a perforation or seat 17 in one. end of the hollow vertical column 18 into I said column, said stem carrying a valve 1.9 capable of closing the said perforation 17 in said column When'the float is spaced a certain distance the'reabove The column 18 extends through-the steam chest 7 andsteam passageway 6 and beyond saidmemhers and issupported by the steam chest, saidsteam passageway 6 being separated at its mouth 20 from the column '18 by the collar- 21 formed with the spaced ports 22 equidistant one from the other. The column 18 beyond the passageway '6 is flared outwardly to form a water reservoir and passageway 23 into whicha pipe 24 leads that supplies water underpre'ssure, in cities the purpose being to connect the pipe 21 to the city'mains. An oil pipe or liquid fuel pipe 25 extends intothe lower end of the reservoir and longitudinally through the center thereof to a point below the mOuth QO of the passageway 6 where it opens into a horizontal head 26 formed with four radial openings arranged below the steaniports in collar 21, so that'a vertical plaiievin which any two ofthe oilppenings would lie would also contain two of the steam port's. A i

Secured to the reservoir 23 is a flame spreader 2-7 formed with a horizontal flange 28. the free edge thereof heingnpturiied so that it may receive and retai'n'liquidfuel and'serve as a priming cup and'belovv said flange are two gas jets 29 which will ignite any .{fuel that may pass from the fuel por'ts f in the head 26 or that may d'ripor fall to the base plate 1. Thedome 9 is formed witha plurality of air passagewaysBO and with a plurality ofrspacedvertical recesses 31;

In operation the oil in the priming cup 1 28 is ignited, the gas ignited at the jets 2t) and a small amount of oil admitted through the pipe which passing out through the radial openings in the head 26 will burn upon or about the lame spreader and so get the burner hot. A small stream of water is now admitted through the pipe i2-lwhich will till the reservoir 23 and pass up andabout the head 26 and out through the opening 1? in the column 18 into the dome t). The heat from the burning iuel por then being consumed in the flame of the burner. This flame spread by the member 27 will envelop the jacket 3, i and air pipes 2 and pass up and about the dome 9, in the recesses 31 thereof which facilitate heating of the water therein and vaporizing the same. Air passing through the many air pipesand water being fed into the dome will prevent too great heat development while an'excess of water will be prevented by the lloat which would then rise and close the port 17in the column 18. An overflow pipe, not shown, will lead from the plate 1. The oil from the ports in the head 26 receives the dry steam from the steam ports .22 which vaporizes the oil in the atmosphere raising its clliciency as a fuel to a very high degree.

that is claimed is:

1. In an oil burner, a base plate, air pipes leading up and toward each other from said base plate, a water jacket for said air pipes, a steam chest supported by said water jacket, a steam passage 'ay integral with said steam chest, a column extending through said steam chest and said steam passageway and formed with a valve in one end, a dome carried by said steam chest and receiving the valved end of said column, a water pipe connecting said dome and water jacket, a steam pipe opening into said steam chest and in said dome at the apex thereof, a valve float in said dome operatively coi'itrolling the valve in said column, a water reservoir commumcating with said column, a liquid fuel pipe extending longitudinally through said water reservoir i and opening hori ontally through the sides thereof, steam ports located in the mouth of said steam passageway above the mouth of said liquid fuel pipe, a flame spreader carried by said water reservoir, and gas jets arranged below said flame spreader.

2. In an oil burner, a. base plate, air pipes supported upon said base plate, a water jacket for said air pipes, a steam chest carried by said water jacket, a dome carried by said steam chest, automatic water supply means for said dome associated with said steam chest, said means comprising a column extending through said steam chest, a steam pipe connecting said steam chest and dome, liquid fuel supply means associated with said column and com n'ising ahead formed with ports opening through the sides of said column, st *am exhaust ports to said steam chest disposed immediately above the said head, a flame spreader disposed about said column below said head, gas jets arranged below said flame sprcader, and a water pipe connecting said dome and utter jacket.
